The game’s a-foot and so is Robert Downey‘s jaw!

The Iron Man star was shooting Guy Ritchie‘s new Sherlock Holmes film when the deerstalkin’ detective got knocked for a loop.

In the context of the film Downey was grappling with heavy Robert Maillet who stands seven feet tall when the giant connected with Downey’s jaw – knocking him unconscious.

But Downey, being the trooper he is, refused hospitalization and got right back to work.

How did he accomplish that?

Elementary, my dear Watson. 

He’s a Master Thespian – thank you!
